I would not have this perfect love of ours

I would not have this perfect love of ours
Grow from a single root, a single stem,
Bearing no goodly fruit, but only flowers
That idly hide life's iron diadem:
It should grow alway like that Eastern tree
Whose limbs take root and spread forth constantly;
That love for one, from which there doth not spring
Wide love for all, is but a worthless thing.
Not in another world, as poets prate,
Dwell we apart above the tide of things,
High floating o'er earth's clouds on faery wings;
But our pure love doth ever elevate
Into a holy bond of brotherhood
All earthly things, making them pure and good.
